Saudi Arabia's King Salman discussed the "most prominent developments" in the region in a telephone call from the Turkish president, the Saudi state news agency reported, after U.S. President Donald Trump announced the U.S. Embassy in Israel would be moved to Jerusalem.

The agency gave no further details on the discussions.

Turkish government 'rejects' the U.S. decision to recognize Jerusalem as the capital of Israel and calls on the entire world to show solidarity with the people of Palestine, Turkish presidential spokesman Ibrahim Kalın said on Wednesday.

U.S. President Donald Trump announced earlier on Wednesday the US recognition of Jerusalem as the capital of Israel and instructed the U.S. State Department to begin preparations for the transfer of the US Embassy in Israel from Tel Aviv to Jerusalem.

"We reject and condemn this irresponsible and illegal decision by the U.S. leadership. The whole world must oppose this decision, which violates UN resolutions and international law, and take the side of the Palestinian people," Kalın wrote in his Twitter blog.

"We condemn this irresponsible statement of the US Administration that we learnt with great concern, declaring that it recognizes Jerusalem as the capital of Israel and it will be moving the US Embassy in Israel to Jerusalem. This decision is against international law and relevant UN Resolution, as the annexation of Jerusalem by Israel has been rejected b the international community and the UN," Foreign Minister Mevlut Çavuşoğlu said in a statement.
